DUMPING-CAR.

Specification of Letters Patent.

Patented Nov. 26, 1907.

Application filed March 20, 1907. Serial No. 363,438.

in dumping cars and consists in certain features of construction and combinations of parts as will be hereinafter described and pointed out in the claims.

In the accompanying drawings, Figure 1 is I a view of a portion of the center sill of a steel dumping car. Fig. 2 is a plan view of two of the dumping doors and Fig. 3 is a trans- Verse section of the dumping doors, and center sill. Fig. 4 is a modification.

A represents the center sill of a steel dumping car. This sill is preferably a box girder of sufficient strength to carry substantially the entire load of the car body and its contents.

B are cross-sills which are supported on the top of the center sill and are firmly secured thereto in any desired manner. Cross-sills B may be made of channels as shown, or may be made of I-beams.

O is a bracket which is constructed to seat against the plain flat side of the cross sill so as to form a support therefor. Bracket O is riveted to the cross sill as shown and is also riveted to the center sill. Against the opposite side of the cross-sill is seated a bracket E which is constructed to fit against the channeled side of the cross sill. The side of the bracket E adjacent to the channeled side of the cross sill is constructed with a recessed bottom flange a which fits and rests upon the lower flange b of the cross-sill. This bracket is riveted to the cross sill and also to the center sill.

Between the cross sills is located a bracket F of any desired form and construction and which is riveted to the center sill. Each one of these brackets is provided at its upper end with a cylindrical bearing 0 in which is mounted the rod G on which the dumping doors H H are hinged. Instead of providing three brackets between the adjacent cross sills two brackets might be sufficient in some Fig. l represents the channel brackets provided with an elongated bearing which extends throu 'h a hole formed in the Web of the cross sill. This elon ated bearing permits the adjacent ends of two rods G to be supported by a single bracket. If desired a single rod of sullicient length to support the entire series of doors, or any number of the series may be used. The brackets not only serve to support the rods G on which the dumping doors are hinged, but also serve as braces to resist the pulling and bulling strains to which the cross-sills are subjected and retain the latter against injury or displacement.

II II represents two hinged lates which are j ourna ed upon the rod G. ach hinged plate is preferably formed of cast metal, and is constructed with a series of cylindrical bearings h which are mounted upon the rod G, the bearings h of one hinged plate interrepresented in Fig. 2 of the drawings. Each hinged plate is constructed at its outer edge with a depending strengthening rib J, and with a series of lateral strengthening flanges K extending from the cylindrical bearings it, to the strengthening ribs J. To each one of the hinged plates is riveted one of the dumping doors H by rivets is passing through the door and through the hinged plate between the strengthening flanges K. The adjacent edges Z, Z, of the hinges are located in close proximity to each other and effectually prevent the escape of any material through the joints of the hinged plates. This construction of hinged plates for the doors is extremely light, strong and durable and can be produced at a comparatively small initial cost.

Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is

1. The combination with the center sill and cross sills, of door sup orting brackets secured to both the cross s1l s and center sill, substantially as set forth.

2. The combination with the center sill and cross sills, of door supporting brackets constructed to seat against the webs of the cross sills, and riveted thereto, and to the center sill, substantially as set forth.

3. The combination with the center sill and cross sills, of door sup orting brackets constructed to seat against t 1e cross sills and upon the center sill, and secured to both sills,

secting with those on the opposite plate as a rod mounted in the upper ends of said I brackets, and dumping doors hinged to said 10 secured to the under face of each door, said hinge plate provided at their inner edges With bearings mounted on said rod under the inner edges of the doors.

In testimony whereof, I have signed this specification in the presence of tWo subscrib- 15 ing Witnesses.
